Hello Lucja,
Looks like a very peaceful scene, I like the soft illumination and light blanket of fog hovering over the land. I feel the crisp cold air on my neck and smell it's freshness. I can also envision a deer stepping out of the tree line at any moment. Beautiful capture!!

Hi Lucja,
A little bit of fog can do magic to a lanscape and to a photo. You were at the right time and at the right location to capture it. Maybe you could darken the sky a little so there is more focus on the fog.
TFS,
